Back Instability Definition

The spine has several stabilization systems in place to provide support for the spine, including the spinal muscles, the spinal cord, and the boney spinal column. When spinal joints gain too much flexion or become dysfunctional, the spine can destabilize, causing excess motion and leading to lower back pain. Osteophytes (bone spurs) sometimes form to provide stability, which may in turn become a source of pain.
